IMPROVEMENT IN LOOM-SHUTTLES.

Specification forming part of Letters Patent N o. 147,075, datedFebruary 3, 1874; application liled December 1, 1873.

To all whom it may concern :v Y

Be it known that I, EDWTN G. SPALDING, of Lowell, in the county ofMiddlesex and State of Massachusetts, have invented a new and usefulImprovement in Teavers Shuttles, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawing making part of this specification, in which- Figure l representsa plan or top view; Fig. 2, a side elevation; Fig. 3, a plan with anordinary friction device. Fig. 4 is a bottom side ew, and Figs. 5 and 6are each a cross-section of Figs. l` and 3, respectively.

This invention is intended as an improvenient on my former one, theapplication for which bears date November 24, 1878; and relates .to themeans for threading a shuttle which has a bottom eye and a side eye, thelatter opening into the former.

The object of this invention is to facilitate the process of threadingthe shuttle having the bottom and side eyes, as described, and toobviate the necessity of sucking the filling through, with injury to theoperative from the dust and linty bers drawn into the throat and lungs.This invention consists of a slot, g, form ed in the under side of theshuttle, through the substance thereof, into the side eye c, from itsYoutlet to the bottom eye, or to the recess F below-the bottom eye, thusforming a passage for the lling from the bottom eye to the eye in theside of the shuttle.

In the said drawings, A represents the body of the shuttle, and B thecop or bobbin on the spindle C. The bottom eye l may open into a recess,F, or the recessmay continue through the bottom of the shuttle and formthe bottom eye, and then the side eye will open into the bottom eye. Solarge a bottom eye will furnish abundant room for the passage of thefilling, the end of which is easily passed through, and then drawnthrough the slot g into the side eyec, and the shuttle is threaded. Theeye cis formed at an angle both inward and downward, as shown, and theslot g is at o r near the same angle with the eye c and with the side ofthe shuttle. VVhenthe shuttle passes through the open shed of thedivided warp, the lower division of such warp is drawn across the raceof the lay, which is the path of thc shuttle, and there is no liabilityof the lower warp-threads catching in the slot g in the uuder side ofthe shuttle, even though such slot was at a right angle with the side ofthe shuttle, whereas, if the slot was in the top edge of the shuttle, asit is in some cases, the warpthreads in the upper division, having nobearing, would be liable to catch in the slot and be severed; and,besides this, they wouldv retard the motion of the shuttle, or cause itto stop in the web.

For the above reasons I consider the slot g in the bottom of theshuttle, and forming a communication between the bottom eye and sideeye, a very important, new, and useful element for the purposedescribed.

This shuttle may be provided with a common friction device, such as isdescribed in my former application, and shown in the drawings of this,and such friction device will operate to advantage in either shuttle,although it does not aid in the process of threading the shuttle.

I claim as my invention- A shuttle having its eyes constructed andarranged, with relation to each other, as dcscribed, and with the sideeye slotted.
